  • The purpose of luminance measurement in lighting design of urban scale is to prevent light trespass and light pollution, caused by over-bright. Specially, the illumination of road, tunnel and sports complex as urban infrastructure is measured by international standard for illuminance and luminance. It has been used the spot luminance meter and the image photometer to define the characteristics of qualitative and quantitative in exterior lighting. This study introduced the concept of HDR Image, procedure of HDR Image creation and analysis. Applications of HDR Image, particularly within the apartment building exterior lighting design analysis, have been demonstrated. The procedure proposed in this study is a affordable method that is useful for the assessment of luminance distribution in the scene with electric light. It also provides a measurement capability with the high resolution luminance data within a large field of view efficiently and quickly, which is not possible to achieve with a luminance meter.

  • The curriculum analysis of lighting design course in the Interior architecture departments in American universities reveals they share a major concern in the basic lighting theories, the sorts of light source and lighting equipment, daylighting, and interior lighting plav. The curriculum is usually composed of two semesters, the first semester being about lighting theory and simple project, while the second one abut more professional fields of design studio. The curriculum of lighting design at the Interior architecture departments in Korean colleges and universities usually consists of introductory courses in the field. Almost every institution allocated only one semester for the courses, and as the courses should cover the broad range within a short time, they were lacked in the required depth and systematic approach. The analysis also reveals the curriculum in Korea puts emphasis on the interior lighting equipment design, while disregarding the importance of daylighting. In comparison, American institutions have their curriculum focused upon the use of daylighting. The curriculum of lighting design courses in Korea, a major part of space rendering methods in the field of Interior Architecture, should be improved without delay. The courses should be included in the required subjects and the educational aims should be changed from offering a general understanding of the concepts to providing professional knowledge and skills, which would contribute to the competitiveness of the departments.

  • In this study, we derive an evaluation structure and 18 Valuation vocabulary for the media facade lighting conditions. In addition, this study deduced the applicable elements that could be applied in time of building nightscape lighting design using media facade by conducting affective evaluation. The research results are as follows: It was found that the image axis of "Dynamic, Colorful" showed the lighting change speed was fast with diverse application of lighting color, and its evaluation object applied by general emphasis, vertical emphasis, partial emphasis lighting method was highly assessed. In addition, it was found that "Luxurious, Unusual" axis showed lighting change speed was slow with the application of lighting color in warm hue series, and its evaluation object applied by line lighting, dot lighting, general emphasis lighting methods was highly assessed. Lastly, it was found that "Soft, Secure" image axis showed the lighting change speed was slow with the application of pastel tone lighting color, and the evaluation object applied by general emphasis lighting method was highly assessed.

  • Based on the trend of architectural lighting of residential building, this study is to examine architectural lighting for residential buildings, and deduce the value and significance of architectural lighting by analyzing architectural lighting and characteristics of residential building through the analysis of works according to the types of works and by analyzing discourse relating to works of architectural lighting of residential building. First, architectural lighting for residential buildings can be categorized according to continuity and extensibility, lighting method and lighting factor. Second, architectural lighting of residential building has come into play since 2000 due to diversified activities at home. Third, architectural lighting had been introduced for living room and used in the form of structure or foundation up until early 2000s, but since mid 2000s, it has been used in intellectual and abstract form using various shapes, finishing material or objects. Fourth characteristic is a space of changing functions overcoming limited space, suggesting an alternative space, and using finishing material and object.

  • Nighttime construction is being adopted by many state DOT's as a way to mitigate the impact of construction operations on the traveling public. Although a number of states have developed standard specifications for nighttime lighting, these standards are usually in the form of generic requirement statements that only specify minimum illuminance levels. The lighting standards do not include specific ways to achieve this illuminance level such as lighting arrangements and configurations for various work zone plans and construction operations. This leaves confusion between the traffic engineers and the contractors and does not guarantee consistency in those plans, thus affecting productivity and safety (lighting conditions account for 18% to 28% of work zone accidents). The main objective of this study is to utilize three dimensional animation and lighting analysis software to study and model lighting conditions of a construction site. This is expected to increase the safety and productivity of construction operations by achieving consistency in work zone lighting schemes. A computerized model was developed, called Nitelite. Various lighting schemes can be studied using the software to provide for typical applications including lighting fixture's locations, luminance, mounting height, tilt angle, and fixture type. The results from the developed software tool were validated through comparisons with previous research conducted using field measurements.

  • Low road lighting is a lighting device that complements the shortcomings of existing pillar-type street lights. It is a lighting device that emits light from the side of the road surface and adjusts the luminance of the road surface like a light carpet. In this paper, to achieve full commercialization, we analyzed the luminance of the installed road surface and studied whether lighting could replace existing road lighting. In this study, the LMK (Luminance Measurement Camera) LABSOFT program was used to measure and analyze the surface luminance of road lighting, and the RELUX program was used to evaluate and analyze the simulation performance to determine light-based lighting conditions. A study was conducted to determine whether replacing pillar-type road lighting with low-level road lighting in a real environment would ensure comfortable and safe night vision for drivers at night.

  • 도시의 환경조명은 야간의 도시를 빛으로 장식하고 미화해서 아름답게 하며, 시민의 안전과 치안을 향상시켜 도시의 품위를 높여 주고 있다. 공원의 조명계획을 수립할 때 공원의 기능이나 성격을 충분히 고려해서 가장 좋은 조명효과를 얻을 수 있도록 조명방식을 이용하는 것이 중요하다. 또한 도시의 야간활동 증대와 경관에 대한 중요성이 높아지는 요즘 도심하천과 해안 수변공간에 대한 경관조명은 기능적인 측면과 더불어 주체성 향상에 중요한 역할을 한다. 이 논문은 수변에 접해 있는 홍콩의 흥험 산책로를 통해 침사추이 산책로 까지 중요 지점에서 조명을 실측 하였고, 일본의 후쿠오카 나카가와 공원을 중심으로 중요 지점으로 파악되는 장소에서 조명 측정을 하였다. 그리고 제주시 함덕해수욕장 진입로 주변과 상가와 인접한 도로를 중심으로 실측하여 조명환경 특성을 비교 분석을 하였다. 분석 결과 홍콩의 경우는 8개 평가항목에서 우수하였고, 후쿠오카의 경우 5개 항목에서 양호함을 보여 보통으로 분석되었다. 그리고 제주시의 경우는 다수의 항목에서 보통과 미흡으로 평가되어 전체적으로 열악한 실정으로 판단되었다. 이를 통하여 지역 주민의 야간 활동을 고양시키고 방문자들에게 아름다운 경관을 제공할 수 있는 제주시 수변공간의 안정적인 조명계획을 제안하고자 한다.

  • Recent high oil price results in the development of energy saving technology such as LED lighting system. Street-lighting system using COH LED package can save energy because the heat dissipation through cupper base is better than conventional technology. Studies on manufacturing processes of lighting system are insufficient even though LED package design and its heat analysis have been studied. This study focuses on the problem and solution of manufacturing processes such as LED packaging process, optimized emission angle, and LED bar dimension for mechanical assembly. As a result, we established better manufacturing alternatives of LED packaging and street-lighting system with higher lighting efficiency of 84 lm/W, as well as good illumination intensity of 39.7 lux at 6 m from lighting source.
